Pyromorphite is a mineral that belongs to the apatite group and is primarily composed of lead phosphate. It typically forms in the oxidation zones of lead deposits and is known for its vibrant green, yellow, or brown colors. The mineral often appears as hexagonal crystals or as granular masses, making it a popular specimen among collectors. This mineral is not only valued for its aesthetic appeal but also for its significance in geology and mineralogy. Pyromorphite can be an indicator of the presence of lead ores and is sometimes used in the study of mineral formation processes.
